(E) The Permittee maintains records of all information regarding the choice of emission limits.

[§63.10030(e)(7)(iii)]

d. During periods of startup of an EG U:

i. The Pennittee has chosen to comply using the following work practice standards, by choosing to comply using paragraph (l) of the definition of"startup" in §63.10042, defined as follows.

Startup means either the first-ever firing of fael in a boiler for the purpose of producing electricity, or the firing of feel in a boiler after a shutdown event for any purpose. Startup ends when any of the steam from the boiler is used to generate electricity for sale over the grid or/or any other purpose (including on site use). Any fraction ~fan hour in which startup occurs constitutes a fall hour of startup.


The Permittee shall operate all continuous monitoring systems (CMS) during startup, except during periods of bypass of the main stack as provided in §63. lO0lO(a)( 4). For startup of a unit, clean fuels must be used as defined in §63.10042 for ignition. Once the unit converts to firing coal, the Permittee shall engage all of the applicable control technologies except the SCR. The Permittee shall start the SCR system appropriately to comply with relevant standards applicable during nonnal operation. The Permittee shall comply with all applicable emissions limits at all times except for periods that meet the applicable definitions of startup and shutdown in Subpart UUUUU. The Pennittee shall keep records during startup periods.

ii. If the Permittee chooses to use just one set of sorbent traps to demonstrate compliance with the applicable Hg emission limit, the Permittee shall comply with the limit at all times; otherwise, the Permittee shall comply with the applicable emission limit at all times except for startup and shutdown periods.

m. The Permittee shall collect monitoring data during startup periods, as specified in §63.10020(a) and ( e). The Perm:ittee shall keep records during startup periods, as provided in §§63.10032 and 63.10021(h). The Pennittee shall provide reports concerning activities and startup periods, as specified in §63.1001 l(g) and §63.10021 (h) and (i). All periods of bypass of the main stack shall be reported as deviations as provided in §63.10010(a)(4)(ii).

(§63.999l(a)(l) and Table 3 to Subpart UUUUU]

e. During periods of shutdown of an EGU:

Shutdown means the period in which cessation of operation of an EGU is initiated for any purpose. Shutdown begins when the EGU no longer generates electricity or makes useful thermal energy (such as heat or steam) for industrial, commercial, heating, or cooling purposes or when no coal, liquid oil, syngas, or solid oil-derivedfael is beingfired in the EGU, whichever is earlier. Shutdown ends when the EGU no longer generates electricity or makes usefal thennal energy (such as steam or heat) for industrial, commercial, heating, or cooling purposes, and no fuel is being fired in the EG U Any fraction of an hour in which shutdown occurs constitutes a full hour of shutdown.

1. The Pennittee shall operate all CMS during shutdown, except during periods of bypass of the main stack as provided in §63.10010( a)( 4 ). The Permittee shall also collect appropriate data, and shall calculate the pollutant emission rate for each hour of shutdown for those pollutants for which a CMS is used. While firing coal during shutdown, the Permittee shall vent emissions to the main stack(s) and operate all applicable control devices and continue to operate those control devices after the cessation of coal being fed into the EGU and for as long as possible thereafter considering operational and safety concerns as provided for bypass of the main stack in §63.10010(a)(4). In any case, the pennittee shall operate the controls when necessary to comply with other standards made applicable to the EGU by a permit limit or a rule other than Subpart UUUUU and that require operation of the control devices. All periods of bypass of the main stack shall be reported as deviations as provided in §63.10010(a)(4)(ii).

n. If, in addition to the fuel used prior to initiation of shutdown, another fuel must be used to support the shutdown process, that additional fuel shall be one or a combination of the clean fuels defined in §63.10042 and shall be used to the maximum extent possible taking into account considerations such as not compromising boiler or control device integrity.

m. The Permittee shall comply with all applicable emission limits at all times except during startup periods and shutdown periods at which time the Permittee shall meet the work practice standards. The Pennittee shall collect monitoring data during shutdown periods, as specified in §63.10020(a). The


Pennittee shall keep records during shutdown periods, as provided in §§63.I0032 and 63.1002l(h). The Pennittee shall provide reports concerning activities and shutdown periods, as specified in §§63.1001 l(g), 63.10021(i), and 63.10031.

[§63.9991(a)(1 ), §63.10042, and Table 3 to Subpart UUUUUJ

General Compliance Requirements [ISA NCAC 02Q .0508(f)] f. The Pennittee shall comply with the General Provisions as applicable pursuant to Table 9 to Subpart

UUUUU. [40 CFR 63.10040]

g. The Pennittee shall be in compliance with the emission limits and operating limits in Subpart UUUUU. These limits shall apply at all times except during periods of startup and shutdown; however, for coal-fired EGU s, the Permittee shall be required to meet the work practice requirements in Table 3 to Subpart UUUUU during periods of startup or shutdown. [§63.l OOOO(a)]

h. At all times, the Pennittee shall operate and maintain any affected source, including associated air pollution control equipment and monitoring equipment, in a manner consistent with safety and good air pollution control practices for minimizing emissions. Detennination of whether such operation and maintenance procedures are being used will be based on information available to the EPA Administrator which may include, but is not limited to, monitoring results, review of operation and maintenance procedures, review of operation and maintenance records, and inspection of the source. [§63.lOOOO(b)J

i. For coal-fired units, initial performance testing is required for all pollutants for the affected EGUs to demonstrate compliance with the applicable emission limits. [§63.IOOOO(c)(l)]

J. The Permittee shall demonstrate compliance with the filterable particulate matter (PM) emission limit through an foitial performance test and shall monitor continuous performance through use of a PM continuous emissions monitoring system (PM CEMS). [§63.lOOOO(c)(l)(iv)]

k. The Permittee shall demonstrate initial and continuous compliance by conducting an initial and periodic quarterly performance stack test for HCJ. [§63.IOOOO(c)(l)(v)]
